I was about to leave my office _____i was told that the president would visit our company.
A. while B when C as D if
麻烦讲解一下这道题。
讲解呀！！！
是B没错！但为什么呀！！！

Answer 1

C
1.首先排除while :两个同时发生的事件如果都没有延续性（leave 和 tell 都是瞬间动作动词），用when或as，不用while。

2.不强调特定的时间性，只是说明两个紧接着的动作时，多用as;As I was going out，it began to rain.当我出门时，开始下雨了。（强调两个动作紧挨着。）
与例题比较：I was about to leave my office _____i was told that the president would visit our company.

Answer 2

明明就是B

Answer 3

when

Answer 4

我刚要离开办公室就被告知主席要来我公司访问。
应该选B

Answer 5

应该是WHILE.WHILE是与此同时之意,全句的意思是我正准备离开办公室的时候与此同时,我被告知主席会来我们公司参观

Answer 6

when ,表示就在这时
